Respiratory magnetometers are increasingly being used in sleep studies to measure changes in end expiratory lung volume (EELV), including in obese obstructive sleep apnea (OSA) patients. Despite this, the accuracy of magnetometers has not been confirmed in obese patients, nor compared between genders. Thus, we compared spirometer-measured and magnetometer-estimated lung volume and tidal volume changes during voluntary end-expiratory lung volume changes of 1.5L, 1L, and 0.5L above, and 0.5L below, functional respiratory capacity (FRC) in supine normal weight (BMI<25kg/m(2)) and healthy obese (BMI>30kg/m(2)) men and women...

Modern spirometry, like no other monitoring technique, allows insight into breath-to-breath respiratory mechanics. Spirometers continuously measure volume, airway pressure, and flow while calculating and continuously displaying respiratory system compliance and resistance in the form of loops. The aim of this case series is to show how observation of spirometric loops, similar to electrocardiogram or CO2 curve monitoring, can improve safety of anesthetic management in small animals. Spirometric monitoring cases described in this case series are based on use of the anaesthesia monitor Capnomac Ultima with a side stream spirometry sensor...
